Abstract

The invention relates to an underwater object locating device, belonging to the technical field of underwater navigation location. The device consists of an emitter 1, an acceptor 2, a data sampling device 3 and a data processor 4; wherein, the emitter 1 consists of a signal generator 1-1 and a pair of emission electrodes 1-2. The acceptor 2 consists of a receiving electrode 2-1 and a receiving circuit 2-2 which are arranged in array. The data sampling device 3 is used for converting an analog voltage signal output from the receiving circuit into a digital signal, and is interconnected with the data processor 4 by a computer external bus. The data processor 4 is used for processing voltage change signals output by the array of the receiving electrode, thus locating the object body. The device has the advantages that 1. the device is a low frequency system, and closer distance high frequency radioacoustic position location has the characteristics of simple structure of hardware, high efficiency of energy and the like; 2. the device can locate based on the change of detection electric field, thus overcoming the problem that the visual field is limited by optical location.

Description

technical field

[0001] The invention relates to an underwater target positioning device. In particular, it relates to an underwater array type active electric field short-distance target positioning device, and belongs to the technical field of underwater navigation and positioning. Background technique

[0002] The 21st century is the century in which mankind marches to the sea. As an important means of exploring the ocean, even in some cases the only means, underwater robots play a very important role in the development and utilization of oceans. One of the key technologies for the engineering and practical application of underwater robots is underwater navigation and positioning technology. It is used to study the global navigation of underwater vehicles in complex ocean environments (long-distance navigation from several kilometers to 1 meter) and local environment short-distance positioning (short-distance is generally less than 1 meter) precise positioning technology...
